To all whomz't may concern:

' Be it known that we, ARTHUR N. GOQDWIN and WILLIAM SUTHERLAND, bothsubjects of the King of Great Britain, and residents of the city ofMontreal, in the Province of Que-.-

bee and Dominion of Canada, have invented certain new and usefulImprovements in Dirigible Headlights, of which the following is a full,clear, and exact description- This invention relatesto improvements indirigible headlights, and the object of the invention is to provide asimple, inexpensive The device consists briefly of a bracket for eachlamp adapted to be attached to the chassis of a car and having the lampcarrying members revolubly mounted therein in a manner to avoid rattlingdue to ordinary vibrations of the car. The lamp carrying members areoperatively connected across the car and one of them is connected bymeans of a telescopic member directly with a lever at the bottom ofthe'steering post. The telescopic operation of the connecting member iscontrollable by the driver of the vehicle to connect the lamps with anddisconnect the same from the steering gear. Means are also rovided tohold the lamps normally aligned with the car.

The stems 19 of the lamp forks 20 are provided adjacent the forkswith a collar or shoulder 21 carrying a ball race 22 corresponding withthe ball race at the upper end of the bracket.

This bracket in- 23 may be drawn together, so as to hold the stemtightly in the bracket and prevent any rattling due to vibration. Thearm 24, which is of any. suitable shape, is pivotally connected at itsfree extremity to one end of a telescopic member comprising a tubularportion 25 and a rod 26 sliding therein. The

connected to the steering arm 13. The tubular member 25 is provided witha small housing 27 containing a spring-pressed locking pin 28 adapted toenter a slot 29 in the rod 26. This locking pin may be operated by thedriver by means ,of a wire 30 passing through a flexible conduit 31extending to any suitable point, such as the upper part of the post 12,where the conduit may be rigidly connected to the casin of the post andthe telescopic member is end of the wire provi ed with a handle 32. r

The pin 28 is preferably thin and flattened and, when in engagement withthe rod 26,,is disposed 'edgewise with reference to. longitudinalmovement of the rod so as to form a strong connection between the rod 26and tube 25. The parts 25 and 26 may be conveniently disconnected bpulling on the wire 30, so as to retract the pm, and tlienturning thewire through 90 to turn thepin across cannot enter.

Each stem 19 1s point with the short arm or lug 33' to which a rod 34may be connected to link up the two" lamp supports, so that rotationtransmitted I to one by the telescopic member andcrank 24 will betransmitted by the link 34 to the other lamp.

In order to hold the lamps against slight oscillations due to vibrationor to minor movements of the wheels in pasing over a bracket in which itturns.

rough road, a latch 35 is provided to re leasably connect each stem 19-with the This latch may be of the bullet type illustrated convenientlyof any other suitable in Figure 3, or may be construction.

The stem and lamp carried thereby will thus be turnedproportionately to the turning of the wheels, which are operativelyconnected to the member 13 or to a similar member. The movement imparted to one stem 19 is transmitted across the car tothe other stem bymeans of the rods 34, so that both lamps oscillate in unison with oneanother and with the front wheels. When driving on a rough road, the

lam s and their turning mechanism are entire y relieved of road. shockandvertical movement of the front axle and also of small oscillatorymovement of by' reason of the connection direct to the steeringarm,which connection is entirely independent of connection between thesteering arm and wheels. When driving on i a straight road,,the latches35 will hold the lamps axially parallel and directed straight ahead ofthe car and also hold them against responding to small movements of thewheels, which are permitted by slackness in the steering gear. Thedevice may be very easily and quickly rendered either operative orinoperative. The slot 29 and pin 28 are located to register when thelamps, are directed straight ahead and the-steering arm also set formovement straight ahead Thus, the parts 25 and 26 are normally inposition to be locked together by the pin 28. If the pin should fail tomesh with the slot imthe desired meshing may be pro- 28 and disconnectthe which the front wheels vduced by slightly rocking the steerin wheel.Disconnection of the parts 25 an 26 to render the lamps stationaryrelatively to the car may be effected in any position of the car or:steering mechanism, but the disconnection is preferably efl'ected whenthe car is l travelling strai ht ahead, so that the lamps will beautomat1cally locked in this position by the latches 35. it will beunderstood that many modifications may be made in structural detailssuch 'as the locking means 28 and latches 35 without departing in anyway from thespirit of theinvention.

Having thus described our invention, we claim is 1. A dirigibleheadlight mechanism comprising a steering arm,- a rotatable lampsupport, a hollow member secured to said lamp support and provided witha laterally directed casing closed at its outer end and ,in direct communication with the bore of the hollow member, a second member slidable,port, a hollow member secured to the lamp supportprovided with alaterall directed casing closed at its outer end 'an in directcommunication with the bore of the hollow member, '.a second memberextending from the steering arm and slidable in said hollow member saidsecond member being provided with a narrow elongated slot adapted attimes to be disposed opposite said casing, a latch movable in the casinghaving a sha e complementary to said slot and normal y adapted to enterthe same when projecting from the casing, a spring for projecting thelatch contained within the casing and an actuating stem carried bythelatch mounted for sliding and rotatable movement, whereby the latchmay be retracted from the slot and turned at right angles to its formerposition to prevent reengagement in the slot.

In witness whereof, we have hereunto setour hands.
